Turn the Device off and on. 

If the problem continues, contact the vendor.

I forgot the IP address for the Device.

The default IP address is 192.168.1.1.

If you changed the IP address and have forgotten it, you might get the IP address of the Device by 
looking up the IP address of the default gateway for your computer. To do this in most Windows 
computers, click Start > Run, enter cmd, and then enter ipconfig. The IP address of the Default 
Gateway might be the IP address of the Device (it depends on the network), so enter this IP 
address in your Internet browser. 

If this does not work, you have to reset the device to its factory defaults. See 

.

I forgot the password.

The default admin password is 1234 and the default user password is 1234.

If you can’t remember the password, you have to reset the device to its factory defaults. See 

.

I cannot see or access the Login screen in the web configurator.

Make sure you are using the correct IP address.

• The default IP address is 192.168.1.1.
• If you changed the IP address (

), use the new IP address.

• If you changed the IP address and have forgotten it, see the troubleshooting suggestions for 

Check the hardware connections, and make sure the LEDs are behaving as expected. See the Quick 
Start Guide.

Make sure your Internet browser does not block pop-up windows and has JavaScript and Java 
enabled.
